Memory card game written in Rust with the Slint GUI framework, cross-compiled for the LuckFox Pico Ultra W (ARMv7) — renders at 720×720 via the LinuxKMS software backend, no GPU required.

• Target: LuckFox Pico Ultra W (ARMv7, armv7-unknown-linux-gnueabihf)
• Language: Rust 2021
• UI: Slint 1.14.1 (backend-linuxkms-noseat, renderer-software)
• Cross-compilation: cross tool with ghcr.io/slint-ui/slint/armv7-unknown-linux-gnueabihf Docker image
• Build: Cargo, optimised for binary size (opt-level="z", LTO, strip)

Install cross:

cargo install cross

Build for LuckFox Pico (hard-float ABI):

cross build --target armv7-unknown-linux-gnueabihf --release

Deploy and run on device:

scp target/armv7-unknown-linux-gnueabihf/release/memory_slint root@<device>:
ssh root@<device> sudo ./memory_slint
